Louisiana Teachers Use Professional-Development Day to Protest - Teacher Beat - Education Week
This article ends with a statement about how teachers see professional development as non-essential - something subordinate to other responsibilities. Supposedly, this is unlike what occurs in top-performing countries.
Although I am a big believer in PD and a constant examination/honing of teaching methods, I often find the professional development that I'm asked to sit through VERY non-essential. Most of it has been very passive - exactly the opposite of great teaching. This passive, sit-and-listen type of professional development is probably also very time-effective and inexpensive in comparison to things like lesson studies, teacher observations and debriefings, and other active forms of PD. Another reason PD in the US is so poor is that it seems to have become just another responsibility of already-too-busy administrators. It is an afterthought. And it is an area that, if bettered, could substantially improve teaching and learning in the US. (Although it's NOT an area that seems to lend itself to data collection.)
